Objective: To assess changes in serum albumin concentration (ALB), colloid osmotic pressure (COP), and Doppler blood pressure (DBP) following transfusion of 5% lyophilized canine-specific albumin (CSA) in hypoalbuminemic dogs following surgical source control for septic peritonitis.
Design: Prospective randomized clinical trial November 2009 - November 2010.
Setting: University teaching hospital.
Animals: Fourteen client-owned dogs with hypoalbuminemia (<27 g/L [2.7 g/dL]) following surgical source control for septic peritonitis.
Interventions: Dogs were randomized to clinician-directed therapy (CDT) and CSA groups. Dogs enrolled in the CSA group received 800 mg/kg of CSA within 24 hours following surgical intervention.
Measurements and main results: At enrollment, ALB, COP, and DBP were not different between groups. ALB, COP, and DBP were significantly increased in the CSA group 2 hours following completion of the transfusion compared with the CDT group (P = 0.0234, 0.0078, 0.0156, respectively). In comparison to the CDT group, there was a significant change in ALB in the CSA group 24 hours after transfusion (P = 0.0039), but no difference in COP (P = 0.3914) or DBP (P = 0.5145). ALB was significantly higher in the CSA group at 24 hours compared with the CDT group (P = 0.0367) At the time of death or discharge, there was no difference between groups regarding ALB, COP, or DBP, but an association between ALB and survival was identified (P = 0.0273). One dog experienced tachypnea during transfusion of CSA; this dog died of unknown respiratory causes 120 hours after transfusion.
Conclusions: The administration of CSA in dogs with septic peritonitis results in an increase in ALB, COP, and DBP 2 hours after administration. An increase in ALB persisted at 24 hours compared with a CDT group. Administration of this product was not associated with owner-reported delayed adverse events in this population of dogs.
